This paper investigates an integrated strategy joining non quality effects and preventive maintenance (PM) policy. We consider a single machine subject to random failure rate and producing a progressive deteriorating products. A preventive maintenance (PM) strategy with minimal repair is applied with non negligible durations of maintenance tasks. This study consists on developing an analytical model in order to determine an optimal integrated maintenance plan taking into account the quality deterioration of products. This strategy consist on selling products at a discount price due to the loss of quality caused by the machine degradation. The objective is to determine the optimal number of batches produced N* before each preventive maintenance action which maximize the total profit (PT) per time unit for a full cycle T. A numerical example is presented in order to illustrate the proposed model. A sensitivity study is used to evaluate the influence of model parameters.
